WALTER BENNETT, OF PROVIDENCE, RHODE ISLAND.

SPECIFICATION forming part of Letters Patent No. 273,702, dated March18, 1883.

Application filed October 18. 1882. (No model.)

To all whom it may concern:

Be it known that I, Dr. WALTER BENNETT, of the city of Providence,Stateot' Rhode Island, have invented a new and useful Improvement in aSkin-Puncturing Device or Recussitator, of which the following is aspecification.

The recussitator is an instrument containing about thirty needles, whichhas been used extensively under difi'erent forms and names for thepurpose of perforating the skin, thereby making it the medium of egressfor the deleterious matter in the blood, both with and without externalmedication. By this means the blood may be directly inoculated withsuitableremedies, the action of which in this manner is deemed morespeedy, certain, and efficacious than when taken through the mouth intothe stomach.

The object of my invention is to make the application of therecussitator much more convenient, rapid, and agreeable, also to make itnoiseless and painless, to make it practical for the operator to applyit on any portion of his body or limbs, to make it readily adjustablefor the distance the needles may penetrate, to make it more durable, andto bring its cost within reach of all.

As heretofore constructed the needles in a recussitator are moved in thesame line with the handle of the instrument, which makes it impossiblefor the operator to apply them on his back and arms.

By reference to the accompanying drawings. in which Figure 1 representsa longitudinal sectional view, and Fig. 2 a plan view, it will be seenthat the piece 0, containing the needles I, is placed crosswise of theline of the handle A, which makes it convenient for the operator toapply them on his back and arms.

In the drawings, Fig. 1, it will be seen that the rubber tube F, whichis about one-tenth of an inch in diameter, extends from nearthe handle Ato one-sixteenth of an inch below the points of the needles I, andthree-sixteenths of an inch below the outer casing, D.

Holding the recussitatorloosely by the bandle A, and striking a lightblow, the rubber F will be compressed, so that the needles I maypenetrate the skin as far as the outer casing, D, or their wholeexternal length, oneeighth of an inch. The reaction of the rubber willinstantly release the needles, and also elevate the instrument. Therapidity of action in the manner above stated may he more than doublewhat is possible with recussitators as heretofore constructed.

The wood B, Fig. 1, is made fast in thehan- (lle A. The piece 0, thatretains the needles I, passes through the center of B, and is held inposition by the eccentric K on the thumbscrew G.

H represents a cap to cover the needles.

What I claim is 1. In a recussitator, placing the piece G, containingthe needles I, crosswise of the line of 65 the handle A, Fig.1,substantially and for the purpose specified.

2. In a recussitator, extending the rubber spring F, or any othermaterial con uectcd therewith or withany other spring, below the pointsof the needles I, substantially and for the purpose specified.

3. In a recussitator, the holding and the adjustment of the piece 0 bymeans of the thu mbscrew G and its eccentric K, substantially and 75 forthe purpose specified.
